PRESS- Application filed April 3, 1905. Serial-No. 258,425.

To all whom it may concern:

Be it known that we, JOHN G. .FIDDYMENT,

of Brinkley, Monroe county, ,Arkansas,,and

JOHN J. MoNALLY,of Norfolk, Norfolk county, Virginia, citizens of theUnited States, have invented a certain new and useful Press, of whichthe following is a specification, reference being had therein to theaccompanying drawin s.

This Invention relates to resses, the invention hereinafter particular ydescribed being designed with special reference to that class of ressesem loyed for extracting the juices or liquid or o' from vegetableeseeds,such as cotton-seed, castor-beans, nuts of various kinds, fish, brewersand packing-house prod- 5o scribed, il

nets, and any material containing liquid.

The particular type of press to which this invention relates is thatemploying, in connection with a suitable press-chamber, a feedscrewworking therein and serving to force the material through thepress-chamber, compressing the same and expressing the liquid therefromduring the movement of the material through the press-chamber.

One object of the invention is to provide a feed-screw of special formhaving a portion of its thread so disposed as to establish a receivingthroat or space with substantially parallel sides in which the materialis primarily received as itleaves the supply chute or hopper; also,toprovide means whereby the width of said receiving-space may beincreased and diminished as conditions may require.

A further object of the invention is to provide a check or back-stop atthe receiving end of the press-chamber and means for advancing andretracting said check, whereby the material is admitted to thepress-chamber and held from being rotated with and by the feed-screw asthe latter is actuated; also, to provide means whereby the reach orthrowof the check may be varied to suit the width of the receiving-spaceof the feed-screw.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenove construction, combination, and arran ement of parts, as hereinfully defustrated, and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection through apress embodying the present invention. Fig. 2 is afront end view of the press, omitting the driving-gears and showing thescrew-shaft in section. Fig. 3 is a similar view, omittin thecheck-actuating cam. Fig. 4 is'a detaI perspective view of the head atthe front end of the press-chamber. Fi 5 is a detail pers ective view ofthe chec -actuating cam. ig. Bis an edge view of the same. Fig. 7 is anenlar ed vertical longitudinal section through t e receiving end of thepress-chamber and feed-screw, showin the check and the operating meansthere or. Fig. 8 is a similar view showing the means for var the widthof the receiving-space of the feedscrew. Fig. 9 is an enlarged front endView of the ress-chamber, showing the arrangement 0 the checks and theiractuating-cam.

Fig. 10 is an enlarged detail view of the check.

Like reference-numerals designate corresponding parts in all figures ofthe drawings. The improvements contemplated in this invention aredesigned for use upon the press, (illustrated in Fig. 1,) in which 1designates a feed-screw provided with as ecial form of flight or threadand mounte to work in a casing 2, preferably cylindrical in shape, saidcasing being supported by a suitable frame and the feed-screw beinjournaled in said frame. A simple form 0 frame comprises a series ofbearing standards or pedestals 3, 4, and 5, which are connected andbraced by longitudinal beams 6, the journal portions of the feed-screwbein received in said standards and the casing being mounted upon andsecured to the beams 6, as shown.

Patented March 27, 1906. I

The feed-screw is mounted to rotate within the casing and embodies atapering body or drum 7, which gradually increases in size from thereceiving end of the press-chamber to the discharge or delivery endthereof, a gradually-contracting annular s ace being thus left betweenthe drum 7 an the inner wall of the press-chamber. Thus as the materialis forced through the press-chamber it is compressed more and more, theli uid being expelled through the slatted wal of the casing orpress-chamber and remainder of the the press-chamber.

material from which the liquid has been expressed being forced out ofthe discharge end of the press-chamber through a resistanceplate 8.Stationary bafile projections 9 prevent the material from turmng withthe feed screw as it is forced lengthwise through the press. v

In carrying out the present invention the press-chamber or casing 2 isprovided at the receiving end with a stationary head 10, through whichis formed an opening or gateway 11, in which is mounted a ate or check12, which by projecting into t e receiving end of the press-chamber actsas aback-stop to prevent the material from turning with the feed-screwas the latter revolves within This check 12 is preferabl in the form ofa quadrant, as shown best in Fig. 10, and is hinged or pivotallyconnected at its inner corner 13 to the head 10 along one end of the oening 11, which edge is approximately ra ml to the axis of thefeedscrew 1. The outer face of the check is rounded or described on thearc of acircle of which its pivot is the center, while the side faces 14of the check are substantially at right angles to each other. The outerportion of the check is laminated or of sectional construction, asshown, and the lies (shown at 15) are detachable, being heldiin place onthe body of the check by suitable fastenin s 16, so that one or more ofsaid plies may e removed as conditions may require, as hereinafter exlained.

The flig t or thread 17 of the feed-screw is of uniform pitch throughoutthe major portion of the drum 7; but near the receiving end said threadfor a portion of its length is disposed substantially arallel to thehead of the press-chamber, sue arallel portion being indicated at 18, we the extreme end portion of thethread is pitched at a greater angle, asshown at 19, and terminates in line with the head 10. In this way amaterialreceiving throat or space. 20 is left between the portlon 18 ofthe thread 17 and the'inner face of the head 10, the sides ofwhich spaceare substantially parallel, thus allowing the check to project into thepress-chamber and hold the material from being carried around by thefeed-screw.

The portion 18 of the thread is of laminated orsectional construction,being made up of two or more .plies or thicknesses 21, secured inplaceby suitablefastenings' 22, so that one or more of said plies mayberemoved as conditions require. In this wa the width-of thereceiving-space of the fee screw may be varied to suit the check 12, thefree edge or rounded surface of which swings close to the thread portion18, as shown m' Figs. 7 and 8. Under varying conditions of the materialbeing fed to the press it is desircreasing the width of thereceiving-space 2O and correspondingly increasing or decreasing thereach of the check, which is done b adding or removing one or more ofthe p ies 15 and 21. The supply chute or hopper 23 leads into thepress-chamber directly in line with the receiving-space of thefeed-screw, as shown in Figs. 1, 7, and 8.

As the feed-screw revolves the extreme portion 19 of the thread 17 comesin contact with the inner side face of the check and swings the checkoutward and passes by the same. The check is returned or swun inward bya cam 24, mounted onthe eedscrew shaft or extension outside of thepresschamber, which cam acts against the opposite or outer side of thecheck, as will be apparent in Fig. 7. In this way the check isoscillated or advanced and retracted at the proper intervals. In thedrawings we have shown two of such checks; but it is to be understoodthat one or more checks may be utilized as found expedient. I

In order todis ose the portion 18 of the thread substantia ly parallelto the head 10 the thread is necessarily diverted or defiecte from thenormal pitch. In doing this the' portion 18 is preferably made double,consisting of two parts 18 and 18', as shown in Figs. 7 and 8. The spacebetween such portions 18 and 18 does not, however, receive any material,and may therefore be filled up or made solid, if so desired. It will beseen that the portions 18 and 18 diverge from a certain point andconverge and come together at another point, and between such v pointsthey each have a difierent pitch.

In operation the material passes from the chute or hopper into thepress-chamber and into the receiving throat or space 20, where it isacted upon by the check or back-stop 12,

which keeps the material from turning.

around with the feed-screw and enables said screw to urge the materialforward toward the delivery end of the press, the screw acting inconnection with the taperin drum to squeeze and compress the materialand express the liquid therefrom, the li uid passin through the walls ofthe press-chamber an the residue or dry pulp being forced out of thedischarge end of the chamber through the resistance -plate. As thefeed-screw revolves the check is intermittently rocked in and out toadmit the material and then back it up, so that the feed-screw may actproperly thereon in the manner described.
